Answer:
Ex-dividend date is 1st April 2010
The last day to purchase the share and still get the dividend proposed is 31st March 2010
Step-by-step explanation:
The standard is that ex-dividend is two business days before the record date,giving a record date of April 5,2010 which is a Monday,it implies that the 4th Sunday and 3rd Saturday are not considered in the analysis.
Hence the ex-dividend is Thursday 1st of April 2010,as a result,for any shareholder to be entitled to this dividend he or she must have purchased the share of ABC corporation by 31st March 2010, a day before the ex-dividend date.
